Here's the armors portion of the item list. Everything appears in the order
the game stores them internally. Items are briefly explained as needed.

And by the way... due to a bug, evade is useless, and is listed here
only for completeness. Someone apparently fouled up a reference, and
MEvd is used for dodging even physical attacks. It's really too bad, given
the amount of equipment with evade bonuses. On the other hand, nearly all
monsters have 0% MEvd, so you'll almost never have any trouble
hitting them...

Warning: May contain spoilers

Keep in mind that the evade bug
makes evade worthless, reducing the usefulness of shields.
However, each shield that gives an evade bonus (all but
the Ensanguined Shield and the Force Shield) also has a flag
that enables a shield block animation. Some shields with
MEvd also enable a magic blocking animation.

Magic blocking animation

Used by: Everyone but Umaro

Aegis
is Zeus's shield in Greek mythology and bears the head of Medusa
(probably, depending on which myth you ask), which is why it often
negates petrification in other games. It won't prevent petrification
in this one, but the high MEvd makes it extremely useful.

When used as an item, this shield casts
Figa as cast by the user, with
the following exceptions: always inflicts maximum damage
(i.e., no damage variation), ignores target's MDef, ignores 'shell'
and 'transform' status on target, ignores penalty for players
attacking players, unreflectable.

When used as an item, this shield casts
Blizzaga as cast by the user,
with the following exceptions: always inflicts maximum damage
(i.e., no damage variation), ignores target's MDef, ignores 'shell'
and 'transform' status on target, ignores penalty for players
attacking players, unreflectable.

When used as an item, this shield casts
Thundaga as cast by the user,
with the following exceptions: always inflicts maximum damage
(i.e., no damage variation), ignores target's MDef, ignores 'shell'
and 'transform' status on target, ignores penalty for players
attacking players, unreflectable.

Unlike the Flame and Ice Shields,
the Thundergod's Shield has no weakness, making it more
useful as general-purpose equipment.

げんじのたて

Genji's Shield

Genji Shld

Defense: 54, 50 MDef, +20 evd, +20 MEvd

源氏 (Genji) is the title character of
a famous early Japanese novel, commonly referred to as
"The Tale of Genji".

こうらのたて
カッパステータス時に装備すると…

Carapace Shield
If you equip it during kappa status...

TortoiseShld
??? if equipped while an Imp

Defense: 66, MDef 66, +30 evd, +30 MEvd

Absorbs Water,
teaches Kappa x1

Used by: Everyone but Umaro

The listed defense power only applies in
'kappa' status. Otherwise, the shield gives only 1 defense, though
all other effects (including MDef) apply normally.

Though this shield is worse than useless,
put up with it for 256 battles (the wearer must be alive at the end
of each battle) and it becomes the mighty Hero's Shield. Gogo
cannot uncurse it, apparently because the counter is linked to
earning LP, which Gogo does not do.

I got the name "ensanguined"
from the NA version of Final Fantasy XII and claim no credit for
coming up with it. It means "bloodstained" or
"coated with blood", as does the Japanese
name.

The physical defense isn't half bad either,
unlike the Force Shield. Factor in the MEvd, and this is among the
game's best armor.

どうしのローブ

Taoist Robe

Tao Robe

Defense: 68, 50 MDef, +5 mag, +10 MEvd

Used by: Stragus, Relm, Gogo

It's probably Taoist, especially if the kanji
(not given in-game) are 道士, but several Japanese websites give
the kanji as 導士. That's the same as what I translate to
"sorcerer", minus the 魔, so I'm not sure what to think.

クリスタルメイル

プリンセスドレス

Princess Dress

Czarina Gown

Defense: 70, 64 MDef, +1 str, +2 agi, +3 stm, +3 mag

Used by: Relm

Not bad, but the Behemoth Suit utterly
outclasses it, and you're likely to have one before you get a
chance to use this.

げんじのよろい

Genji's Armor

Genji Armor

Defense: 90, 80 MDef, +5 str, +3 agi, +2 stm, +3 mag

Used by: Tina, Lock, Cayenne, Shadow, Edgar, Celes, Setzer

源氏 (Genji) is the title character of

アーマーカッパ
カッパステータス時に装備すると…

Armor Kappa
If you equip it during kappa status...

Imp's Armor
??? if equipped while an Imp

Defense: 100, 100 MDef

Absorbs Water,
teaches Kappa x1

Used by: Everyone but Umaro

The listed defense power only applies in
'kappa' status. Otherwise, the armor gives only 1 defense, though
all other effects (including MDef) apply normally.

Note the full name. Not for no reason is
Relm, female or not, unable to use it. The Japanese definition of
the term is a waist-length strapless bra, or outerwear of a similar
design. I can just picture Edgar drooling, and if you think Celes
made an impression on Lock in the opera scene...

ゴロネコスーツ
トラネコに似せてあるぬいぐるみ

Sleepy Cat Suit
A costume that imitates a tabby cat

Tabby Suit
Resembles a tabby cat

Defense: 54, 36 MDef, +2 str, +2 agi, +2 stm, +2 mag

Negates Poison

Used by: Stragus, Relm

I think ゴロネコ
(GORONEKO) blends
gorone (napping) with
neko (cat), but goro
could also be the sound of purring or of something
fat rolling, which still fits cats.

チョコボスーツ

Used by: Stragus, Relm

Wearers of the Moogle Suit look like
moogles in combat. Too bad the other suits don't do something
similar.

Defense: 128, 90 MDef, +10 evd, +10 MEvd

Used by: Mog, Gau, Umaro

The incredibly high physical defense
lets Mog and Gau reach a total of 255, at which point all
defendable physical attacks inflict 1 damage at most.
